Justin gets back-up from Jaden Smith to deliver the rap part of 'Never Say Never', before he comes toward the end of Usher's 'OMG' performance.
Justin Bieber and Usher show a strong collaboration when performing at 2011 Grammy Awards. Eva Longoria introduces the young singer by presenting a clip from his film "Justin Bieber: Never Say Never" which looks back to a 2007 audition when Justin sang "U Got It Bad" for his mentor.
On the stage, Justin is sitting on a chair with a guitar on his lap and Usher approaches him. "Yeah, that was four years ago. That's how it started," the American singer says about the clip played on screen. "You told me if it was meant to be, we would meet again," Justin tells Usher who responds, "That's right, and now it's your time."
The Canadian singer then performs an acoustic version of his hit single "Baby" before a band of ninjas playing drums show up on stage to open Justin's performance of "Never Say Never". Jaden Smith then joins him on stage to rap his part of the song.
After Justin and Jaden leave the stage, Usher soon follows it up with a rendition of his own song "OMG". Justin then reappears toward the end of the song to show off his dancing skills and deliver the the final bars of the song with his mentor.
